Patent FR-2182592-A1 (FR)
Title: Assembling sand mould or core elements - using an injected thermoplastic material
IPC: B29C65/54
Filed: 1972-02-07
Abstract: Process for assembling foundry core or mould elements which are rigid and have a certain porosity, one of the elements having >=1 sealing hole issuing at a free surface of the second element in which it is formed and at a surface adjacent the other element. A plastic material in a liquid or pasty form is introduced under pressure into each hole from the free surface and the plastic material is made to penetrate into the porous material forming the mould or core elements. The sealing material is a "hotmelt" thermoplastic whose m.pt. is 80-250 degrees C and it is introduced at a low pressure. This gives quickly made and highly resistant connections between the mould or core elements.

Title: Horizontal sugar boiler with transverse heating plates - has reduced height of massecuite and provides good circulation
IPC: B01D9/00
Filed: 1973-08-30
Abstract: The level of the juice does not greatly to exceed the tops of the heating plates which are fixed to the individual steam inlet tubes and to the outlet tubes for the condensed water.
